Chaos
is from Sri Lanka, and uses the Scythe and Genbu Shield as his weapon.
He is one of the executives of the Secret Society, a criminal organization,
who had suddenly and unexplainably lost his memories and became completely
insane. However, his position in the organization was still held and Chaos
entered the second Toshinden tournament. When the Secret Society had fallen
in its conclusion, Chaos had managed to survive somehow and then participated
in the third tournament.

However,
during the events of the fourth tournament, Genma possesses the shield
once carried by Chaos, indicating a high probability that he was killed
by him.

Chaos is
a pretty cool looking character design overall... He's one skeleton of a human
isn't he? He's a convincing "bad guy" for
the Toshinden series, and is an effective design all around... he fits right in
with the rest of the cast. I like his weapon.
